Review:

First Looks (10/10)
When I first bought the E*Tek I was extremely impressed by the stylish metal case (complete with a set of allen wrenches, some o-rings, and a bottle of lube. Out of the box, this gun is just plain sexy. It is smoother then previous egos and has slightly different milling that gives at a very cool look.

Efficiency (10/10)
This gun is extremely effiecient. I use a 48/30 because I'm too lazy to go buy a 45/45 and I can still get off a very large amount of shots. Also, the pressure doesn't effect the shots until there is such a small amount of air left it is practically empty, basically meaning that it will operate at 1000psi with the same effectiveness as at 3000psi. One thing some people may find annoying is that there is no gauge on the regulator but for me it doesn't matter.

Ergonomics (11/10)
When I first picked it up I barely noticed it was there. The grips meld with your hands flawlessly (or they did for me anyways). It also has a handy snath grip on it complete with little grooves for your fingers. The reg is really smooth and is very comfortable to grip.

Maintenance (9.5/10)
The maintenance is very easy. All you have to do is clean the bolt after each day of play and then lube the rammers o-rings. The reason I give it a 9.5 out of 10 instead of a 10 is that there is no included allen wrench to remove the ram cap, so if you don't notice that, then after your first day of playing with it you are often stuck if you don't have a set.

Accuracy (10/10)
Out of the box the gun ws practically dropping ball on ball. Very nice barrel.

Consistency (9/10)
The reg is not very good out of the box but after a day of play, it settles into a +/- 2 or 3 and it is fine.

Speed (10/10)
I think it is very fast. Out of the box I could easily get a consistent 15 BPS on semi. Remember, this is coming from someone who last owned a Diablo Wrath, so I am not the best judge, however, I think it is very fast. Also, the trigger is really easy to adjust, though occassionally the trigger pin comes loose which is annoying, but is a very easy fix.

Conclusion:

If you have the money, this is a great buy, but I can't really say for sure that is much better than a PM6 or a Minion. I give it a 10 but I would have given it a 9.5 because I think a PM6 still might have been a better choice, but it is still a great gun. Hope this helped.

Yea really nice review, like the way you set it up. Glad you like the ETek. For the whole PM6 thing its pretty much what you come from and what the best feel is, althought the Etek is more reliable too ;)

Oh and Jack..If I were you I would trade a shocker for an Etek in a heartbeat. Make sure you shoot one first (Any Ego in that Matter).
